CORRUGATlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 744,231, dated November 17, 1903.

Application filed December 30, 1902. Serial No. 137,113. (No model.)

To a whom it may concern:

Be it known that I, OHARLEs PUDDEFOOT, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Oorrugating-Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to a machine especially designed for crimping or corrugating the bodies of sheet-metal pails or tubs; and it consists in the novel construction of the machine and in the peculiar arrangement and combination of its various parts, as will be fully hereinafter described and illustrated.

In the drawings, Figure l is a plan view of the machine, and Fig. 2 is an end elevation thereof.

In constructing the machine a suitable bed A, similar to the ordinary lathe-bed, is preferably employed, upon which is mounted for longitudinal travel a carriage B.

G is a movable supporting member arranged upon the carriage for transverse In ovement, said member being adapted to slide in suitable ways a, formed upon the carriage.

D is a screw for operating the member 0, swiveled in a bearing 1) on the carriage and having a threaded engagement with the supporting member.

E represents a rotary head provided with a threaded spindle F, (shown in dotted lines in Fig. 1,) and G is a mandrel threaded upon the spindle and carrying at its free end and fixed thereto a fluted roll H, preferably tapering in form.

I designates a frame secured in any suitable manner to the carriage B and provided at its oppositeends, respectively, with aworkholder J, substantially circular in form, and an upright K. The holder described constitutes a support upon whichthe portion of the pail-body adjoining the bottom rests and is provided with a bearing L therein, in which the free or outer end of the roll II is journaled.

P represents a roll-frame located upon the laterally-movable member 0 for rotary admeshing.

justment. As shown, this frame comprises a head-section 0, split, as at f, and arms 01 and e, carrying the bearings Q, in which the cooperating roll R is journaled. The head 0 of the frame engages over a stud 9 upon the member 0 and may be clamped thereto in different position of adjustment by a screwbolt h.

Upon the upright K is arranged an adjustable guide M, against which the upper edge of the pail or tub is adapted to bear. The guide comprises a slotted arm h, secured by a bolt 7Z2 to the upright, a stud or spindle 7L3, projecting laterally from the arm, and a guide member If, adjustable longitudinally upon the stud and adapted to be held thereto in different position of adjustment by a set-screw 72. The member just described is provided with an annular flange 71. against which the outer edge of the pail bears during the operation of the machine in the manner indicated in Fig. 1.

At the opposite end of the frame I and adjoining the combined work-holder and rollbearing J described is a guide T, arranged upon the carriage for longitudinal adj ustment. This guide comprises a swingingarm U, pivoted to a slotted bracket V, which in turn is adjustably connected to the carriage by a bolt WV;

X designates a stop on the bracket V, against which the arm strikes when in its guide-fingerupon the arm adapted to bear against the pail-bottom.

- The fluted rollers as shown are tapered of the same size and arranged, preferably, in a horizontal plane. The central portion only of each roll isfiuted, the flutes or ribs inter- Each roll at its opposite ends has a plain portion or band 2' thereon, the portions upon the roll B being of less diameter than the corresponding bands or portions upon the roll H, as shown.

S'represents a pail mounted upon worksupport J, with its outer edge supported by and bearing against the adjustable guide M, the body of the pail being interposed between the corrugating-rolls. When properly arranged upon the support, the guide T is adproper vertical position, and Y represents a justed so that when the arm is swung upward into a vertical position the fin gerY thereon will bear against the pail-bottom and hold the work in place. Motion being imparted to the roll II through the agency of the spindle and its rotary head, the pail-body will be corrugated in the manner indicated, the cen-- tral portion only of the pail-body being fluted, while the opposite ends thereof, which pass between the plain portions of the rolls, are left smooth, forming the straight edges j.

If it is desired to corrugate a pail of slightlydifferent size or having a slightly-dilferent taper than the pail for which the rolls were originally intended, it may be fluted by the same rolls bya proper ad j ustment of the pailguides. The adjustment is effected by moving the member h" of the guide M laterally, either toward or away from its arm, according to the size or taper, so as to bring the proper section of the pail-body between the rolls. After the guide M has been properly adjusted the guide I is correspondingly adjusted, so that the outer edge of the pail will be caused to bear during the operation of the rolls against the flange h. here pails or tubs of considerably-larger size and taper are to be corrugated, the guide M is adjusted vertically as well as laterally and different rolls are substituted. The new rolls are arranged in operative relation by a proper adjustment of the transverse member 0 and the roll-frame P.

\Vhat I claim as my invention is- 1. In a sheet-metal-corrugating machine, the combination of a driven fluted roll, a carriage adjustable longitudinally relative to said roll, a laterally'movable feed member upon the carriage, a frame adj ustably mounted upon the feed member, and a fluted cooperating roll journaled in bearings upon said frame.

2. In a sheet-metal-corrugating machine, the combination with a fluted roll, of a carriage movable longitudinally relative thereto, a movable feed member upon the carriage, and a cooperating roll journaled in bearings mounted for rotary adjustment upon said feed member.

3. In a sheet-metal-corrugating machine, the combination of adriven fluted roll, and a similar cooperating roll journaled at its ends in a support rotatably adjustable relative to the driven roll.

4. In a sheet-metal-corrugating machine, the combination with a fluted roll mounted in stationary bearings, means for rotating the roll, a carriage movable longitudinally relative to said roll, a laterally movable feed member upon the carriage, a frame mounted upon the feed member for rotary adjustment, and a fluted cooperating roll journaled in bearings upon said frame, said cooperating roll being driven by the driven roll.
